SPECIFICATION forming part ofv LettersPatent No. 292,348, dated January22, 1884.

Application filed August 3,1883. (Model.)

y To all whom it may concern.: l

up and down.

Be it known thatI, JOHN L. PAINTER, of Bellevue, Huron county, Ohio,have invented a new and Improved Foot-Power Hammer, of which thefollowing is a full, clear, and exact description. Y s

The object of the invention is to improve foot-powerhammers, ashereinafter described, and pointed out in the claims. V I

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorrespond-ing parts in both 'gures Figure l is a side elevation of myimproved foot-power hammer, with some parts in sec.- tion; and Fig. 2 isa plan view.

The yhammer-sta a is pivoted at b to the head of a vertical shaft, c,that is fitted in the socket d of the top of the stand e, so as to riseand fall and to turn freely; and the lower end of the shaft has a stepin the lever f, pivoted to the hind leg of the stand at g, and rangingforward and alongside of the anvil-block h, when its free end is to beused by the operator for raising and lowering the hammer, as the workmay demand, by swinging said lever holes, j, is attached to the stand e,and arranged in a slot, k, through said lever j', forV fastening thelever at any point along it by a pin, Z, to set the hammer at therequired height. An arm, m, is attached to the lower endv of shaft cover lever f, which arm is connected by rod n to a lever, o, pivoted onlever f at p, near the anvil-block, where theoperafor turning the'shaftto swing the hammeralong the face of the anvil, the lever f having tormay readily reach said lever to work it a plate, f with a series ofnotches or holes, f2, in any 4one of which-a catch-pin, f3, may be setafter passing through lever o, to lock the,

hammer in any desired position to which it may be swung. Thehammer-staff a is connected to the foot-lever q, that is employed forworking said hammer, b y the cord, chain, or strap'swhich passesthrough-a slot, t, in the hammer-staff, and connects by a ring, u, witha rod, e, on which a coiled spring, w, is fitted to be contracted, whenthe hammer is forced down, forfraising said hammer again. The spring fwbears against the head x of the A bar, z', having a series of 1 shaft cfor its base, and the rodv connects with the free end'of the spring byan adjusting-nut, y, and washer z, which also serve to regulate thetension of the spring for lsetting it properly forA raising up thehammer promptly.

'Ihe shaft c has a vertical extension, a', above the head, about halfthe length of the hammerstaff, and suitably curved backward from saidstaff to support a coiled buffer-spring, b', that arrests the hammer atlthe end of the upstroke without shock orV jar of any consider ableextent, and I makelthe hammer-staff a adjustable forward and backwardwith relation to the anvil by placing the pivot b ofthe staff in slots cof the arms rv of head w, and I provide a thumb or hand screw, d, V onpivot b, for quickly clamping the pivot in the slots at any desiredposition. n

I do not abandon or dedicate to the publi any patentable featuresetrforth herein and not hereinafter claimed, but reserve the right toclaim the same either ina reissue of any patent that may be grantedlupon this application or in other applications for YLetters Patent thatI may make. i

Having thus describedmy invention, I claim as new and desire to secure`by Letters Patentl.v The combination, with the hammer-staff a, havingpivot b, of ahammer-shaft, c, carrying a head, fr, provided withhorizontally` slotted arms x', and hand-'screw d', whereby thehammer-shaft may be brought forward `more or less, as described. 2. ThecombinationV of the hammer-shaft c with the lever f, provided with astep for said vided with a step for thehammer-shaft c, and 7 Y having atits forward end a pivoted adjustable lever, o, to which is pivoted aconnecting-rod, n, extending rearward, and pivoted /roo to an arm, m,rigidly secured to thelower part of the hammer-shaft above its step, aperforated arm passing through said lever f, and :L c, having slottedextension c, and the spring,` 1o pin7V l, substantially as setforth. w,whereby the hammer may be actuated von 4. yThe combination, with thehammer-shaft its downward and upward moxf'oment, as doc, 11a-ving armmf, of the connecting-rodar, lever scribed.
